Too bad you can't give negative stars.
The build is cheap. Like others, I was promised 3 months delivery in early 2013 and the delivery was more than twice that. I bought the 16 foot model. It has so little storage that it's a joke. No useful lower cabinets. No external storage. Only 4 floor tie down points.
We had Problems with the mechanics of the loft bed that we had to troubleshoot ourselves. The wall insulation is thin and spotty.
Like another reviewer, our roof tore within months. The top edge of the aluminum siding was so ragged that it cut through the edge of the roof just from road vibration according to our local repair shop. Dune Sport said we clearly scraped the trailer against something that tore the roof edge. There's no way that could have happened based on how it tore. Our local shop said the roof was incorrectly installed and showed us piece by piece what they did and what should have been done.
I wish I'd forfeited my deposited and walked away from the purchase.
